Can we assign 2 IPs for a SCCM 2012 primary site server and use 1 IP for communicating with its 2 DPs and 2nd one for communicating with its upper hierarchy CAS which is in a different .Domain

Question

Hi,
Can we assign 2 IPs for a SCCM 2012 primary site server and use 1 Ip for communicating with its 2 DPs and 2nd one for communicating with its upper hierarchy CAS . ?
Scenario: We are building 1 SCCM 2012 primary site and 2 DPs in one domain . In future this will attach to a CAS server which is in different domain. Can we assign  2 IPs in Primary site server , one IP will use to communicate with its 2 DPs and second
IP for communicating with the CAS server which is in a different domain.? 
Details: 
1)Server : Windows 2012 R2 Std , VM environment .2) SCCM : SCCM 2012 R2 .3)SQL: SQL 2012 Std
Thanks

Answer 1

First, it's not possible. You cannot attach a primary site to an existing CAS.
Primary sites in 2012 are *not* the same as primary sites in 2007 and a CAS is 2012 is completely different from a central primary site in 2007.
CASes cannot manage clients. Also, primary sites are *not* used for delegation in 2012. As Torsten points out, multiple primary sites are used for scale-out (in terms of client count) only. Placing primary sites for different organizational units provides
no functional differences but does add complexity, latency, and additional failure points.
Thus, as the others have pointed out, your premise for doing this is completely incorrect. What are your actual business goals?
As for the IP Addressing, that depends upon your networking infrastructure. There is no way to configure ConfigMgr to use different interfaces for different types of traffic. You could potentially manipulate the routing tables in Windows but that's asking
for trouble IMO.
